Disk based hashes is a method to create
multidimensional binary trees on disk. This
library permits the extension of the database
concept to a plethora of electronic data, such as
graphical information.

Objective Caml is the latest implementation of the Caml dialect of ML. It has full support for objects and classes combined with ML-style type reconstruction, a powerful module calculus in the style of Standard ML (but retaining separate compilation), a high-performance native code compiler (in addition to a Caml Light-style bytecode compiler), and labeled arguments with possible default value.

tgif is a vector-based drawing tool, with the additional benefit of being sort of a web-browser. That is, you can fetch drawings from a web server with it, and you can make objects in your picture into hotlinks to other parts of the drawing, or to other drawings accessible via HTTP.

JyConsole is an efficient component able to
manipulate Python/Jython and Java objects through
a command line interface. It features several
requirements of modern consoles, such as command
history, completion (Ctrl+Space), easy script
loading, and basic GUI preference management.
JyConsole can be directly used as a standalone
application or as an embedded graphical component
in a Java or Jython application.

The Open Palmtop Integrated Environment aims at
making a universal graphical framework for most
(embedded) distributions available and providing a
basic platform even for professional applications. As
reference platforms, HP's iPAQ and Sharp's Zaurus
PDAs are directly supported.

Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.

JpGraph is an OO graph drawing library for PHP 5.1 and above. Highlights of the available features are: multiple scale types; anti-aliasing of lines; color-gradient fills; support for GIF, JPEG, and PNG formats; and support for multiple Y axes. Many plot types are supported, such as pie-charts, lineplots, bar plots, impulse plots, polar plots, error plots, contour plots, matrix plots, gantt charts, and many more. The pro-version also contains extensive 1D and 2D barcode support. The documentation is extensive and is over 700 pages.

NetSieben SSH Library is a Secure Shell client library for C++. It utilizes the Botan library for its cryptographic functions, allowing a large choice of algorithms to be used in SSH communications. It integrates Secure FTP client functionality and has been tested in multi-threaded applications.

LibreSource is a versatile collaborative platform and software forge. It is adapted to the collaborative software development, groupware, community leading, e-archiving and Web publishing. On a single server, LibreSource can host several projects, several groups of users, and grant fine-grained access to the resources. Based on Java/J2EE technology, it is a modular Web server that users can customize online by combining resources and rights: wiki pages, forum, trackers, synchronizer, subversion, files, download areas, a dropbox, forms, etc.
